IMPROVEMENT IN THlLL-COUPLINGS.

Specification forming part of Letters Patent No. 154,648 dated September1, 1874; application filed July 11, 1874.

To all whom it may concern:

Be it known that I, OLIVER C. CORNELL, of Sing- Sing, in the county ofWestchester and State of New York, have invented a new and valuableImprovement in Anti-Rattler for Shaft-Couplings and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being bad to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a plan view of myanti-rattler for shaftcouplings. Fig. 2 is a sectional view of the same.Fig. 3 is a detail view of the same.

This invention has relation to means for preventing thill-couplin gsfrom working loose and rattling; and it consists in the employment of anindia-rubber block, partly inclosed by a metal spring, which spring isso shaped that it will hug the eye of the thill-iron and I hold therubber block in its place, at the same time preventing the rubber fromundue wear, as will be'more fully explained hereinafter.

In the annexed drawings, A designates an axle B, the embracing portionof a clip, and B the clip-bar or yoke. G is the thill-iron; g,

its eye, and c the bolt which connects the thill to the ears a a of theclip. These parts are all constructed in the usual we1l-known manner. Sdesignates an india-rubber block, presenting a front concave surface anda back flat surface. This block S is inclosed by a metal spring-shield,D, which is shaped somewhat like the capital letter A. One limb, d, ofthe spring is flat, and rests upon the front end of the yoke B, andbears against the front side of the clip. The other limb, d, is curved,and of such length as to extend well beneath the eye 9 of the thill-iron(J, as shown in Fig. 2.

The spring D serves two purposes: it affords a durable andsmoothmetallic surface, against which the eye of the thill-iron playsfreely, and it also securely holds the rubber block S in place by reasonof the front limb, d, hooking under the eye 9. The two springs combined,when compressed between the eye 9 and the clip, prevent rattling, andalso prevent the casual detachment of thebolt c.

I am aware that a rubber block partly inclosed by a guard and secured bymeans of a bolt to a detached clip-bar, as .shown in Letters Patent No.64,219, dated April 30, 1867, is not new. t

What I claim as new, and desire to secure by Letters Patent, isn Thecombination of the'eye g, the thill-iron G, the yoke B, the clip B, themetallic springshield D, inclosing the india-rubber cushion S, havingone end, d, resting upon the front end of the yoke B, and bearingagainst the front side of the clip B, and the other end, d, curved andextending beneath the eye 9 of the .thill-iron G, as shown anddescribed.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

OLIVER o. CORNELL.
